1. Pharynx: a tube-like passageway at the top of the throat that receives air, food, and liquids from the mouth or nose. 2. Epiglottis: a flap of tissue at the lower end of the pharynx that keeps food and liquid from entering the rest of the respiratory system.
Explanation:
Pharynx, (Greek: “throat”) cone-shaped passageway leading from the oral and nasal cavities in the head to the esophagus and larynx. The pharynx chamber serves both respiratory and digestive functions. Thick fibres of muscle and connective tissue attach the pharynx to the base of the skull and surrounding structures.
The statement is probably false knowing that there is a notion of " atrophy" that probably originates from " trophy- trophic" and that if we consider a trophic chain abolished then the biocenoses just adapts before disapearing. If the adaptive process is not compatible to the remaining coordinates then some species would probably have to be protected
The correct answer is this one: "human industrialization." Air pollution comes from human industrialization. Because of too much industrialization, there are a lot of excess and wastes in any form: air or even liquid and solid wastes.
Be cautious of yourself( always be listening to yourself ), when something agitates you take deep breaths before speaking and always think before saying something
